What is a "Regulator" Clock

We often have customers come in with a clock called a regulator.    What is a regulator clock? 
The regulator clock is the invention of the ancient times people.  A regulator clock is useful in both the modern and the traditional times. Regulator clock has made our life useful and manner full by many aspects. Regulator clocks are used throughout the world. The first and the most definition of traditional concept of regulator clock pertain to the scientific concept of a regulator clocks.   The special purpose it has been designed to function with weights and gears to gain a very high degree of accuracy. Regulator clocks are designed to function with high degree of accuracy.
Regulator clocks were first created in 1700s by Englishmen James Harrison and Benjamin Villainy and eventually adopted the technology of Regulator clock by Vienna where the Regulator clock became not only a scientific instrument by also a popular style of clock, using a complex set of pendulum that controlled each of the regulator clock hand. Regulator clocks developing popularity led to three main styles of regulator clock. Business regulator, used to monitor official business practices, astronomical regulator, designed to be highly accurate for scientific purposes, and fashionable regulator clocks. Regulator clocks are used in homes and offices. This style of trend rising in Regulator clock led to the many definition of regulator clock. A brand of Regulator clock eventually developed in the early 1900.  This regulator wall clock was not what is known as the Vienna style anti-regulatory clocks, but were instead produced primarily by the New Haven clock Co. While newer versions, these clocks are also considered antiques, and many are prized by the collector.
Clock before the regulator design were made with anchor style – anchor pendulums.  Regulator clocks, sometimes referred to as pendulum clocks, were invented in the late 18th century in a quest for greater timekeeping accuracy. They were weight-driven devices and featured a deadbeat escapement (an improvement on the anchor design). To ensure their accuracy, they usually omitted complicated features like calendars. Instead, each of the clock’s hands worked off a different mechanism.
Regulators replaced these anchors with a weight – driven mechanism known as a dead beat escarpment, the most advanced version of these clocks version tended to beat escarpment. The most advanced version tended to avoid extra features such as bells and chimes and focus only on accurate timekeeping over a long period. The dead beat escarpment, also known as the Graham escapement, uses a lock and slide mechanism to restore energy to the gears. Pendulum swing different ways for different types of regulators- Vienna regulators for instance have pendulum that swings only a short distance, sometimes with an arc only an inch long. The Evaluation takes place to know how much energy the clock saves.
The escarpment has a verge that is designed to allow the escape wheel {most gear in the regulator clock} to rotate tooth by tooth without allowing energy to escape. This is done with the tiny working face s of the verge, which lock on teeth to them moving only one at one time as the pendulum swings. Additionally, the edges of these working faces, where the tips of the teeth slide along to be locked into place, are specially angled to keep energy from being wasted. The faces give the wheel an extra push with every swing of the pendulum. This makes regulator clock highly accurate but only if they are properly adjusted.


  1. Hi, just passing by to see something very interesting and gladly I've found it here. Thank you for your wonderful article it really helped me a lot. You can also visit my site if you have time.

  2. Here is some information That has been passed on to me by some of my elders. I am not sure of its accuracy.
    I was told that most larger towns had a Regulator clock. When farmer John came to market to sell his goods, he would bring his mantle clock to town. He would go to the town Regulator and synchronize his mantle clock to the Regulator. In this manor the townspeople stayed on the same time.

    I was also told that where the American 2nd Amendment says 'A well Regulated Militia" had nothing to do with rules and regulations, but with timing. There were 17 steps to load the flintlock musket. The Colonial Army determined that they would have to fire 3 shots a minute if they were to be able to defeat the British Army. 17 times 3 is 51, basically 1 step per second. They would have to move like clockwork. If they did not fire three shots in a minute the British Army would be able to over run their position, and bayonet them. People feared the bayonet more that the musket ball because the musket ball made a round hole, which could be sewn into a straight line. The British bayonet was triangular and made a wound that was difficult to sew closed.

  3. I need the cards that are inserted into the bottom window of the 218c. The only one it came with was "Home To Thanksgiving. Thank you

  5. I always read that regulator clocks are weight driven and have pendulum. This makes me think of something like a grandfather or cuckoo clock, but in my mind a regulator clock has a pendulum but no weights; it is wound up w. a key. Am I missing something Here? Thanks, Phil
